Mechanisms of local stress sensing in multifunctional polymer films using fluorescent tetrapod nanocrystals

Номер: US20180045590A1

Nanoscale stress-sensing can be used across fields ranging from detection of incipient cracks in structural mechanics to monitoring forces in biological tissues. We demonstrate how tetrapod quantum dots (tQDs) embedded in block-copolymers act as sensors of tensile/compressive stress. Remarkably, tQDs can detect their own composite dispersion and mechanical properties, with a switch in optomechanical response when tQDs are in direct contact. Using experimental characterizations, atomistic simulations and finite-element analyses, we show that under tensile stress, densely-packed tQDs exhibit a photoluminescence peak shifted to higher energies (“blue-shift”) due to volumetric compressive stress in their core; loosely-packed tQDs exhibit a peak shifted to lower energies (“red-shift”) from tensile stress in the core. The stress-shifts result from the tQD's unique branched morphology in which the CdS arms act as antennas that amplify the stress in the CdSe core. Our nanocomposites exhibit excellent cyclability and scalability with no degraded properties of the host polymer. Colloidal tQDs allow sensing in many materials to potentially enable auto-responsive, smart structural nanocomposites that self-predict impending fracture. 1. A stress sensing nanocomposite comprising:a polymer film further comprising a plurality of aggregated fluorescent tetrapod nanocrystals.2. The nanocomposite of claim 1 , wherein the aggregated fluorescent tetrapod nanocrystals comprise aggregated tetrapod quantum dots (tQDs).3.

Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized A-B-A triblock copolymer resin and/or an A-B diblock copolymer resin into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form the gelatinous elastomer in-situ while simultaneously polymerizing the polyol and the isocyanate to form polyurethane foam. The polyurethane reaction is exothermmic and can generate sufficient temperature to melt the styrene-portion of the A-B-A triblock copolymer resin thereby extending the crosslinking and in some cases integrating the A-B-A triblock copolymer within the polyurethane polymer matrix. The combination has a marbled appearance. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. Another advantage of in situ gel-foam is that the gel component provides higher support factors compared to the base foam alone. 2.

Asymmetric organic-inorganic films and methods for forming and using such films. For example, the films are used as membranes for selective separation applications. The methods combine co-assembly of block copolymer (BCP) and inorganic nanoparticles (NPs), such as, for example, titanium dioxide (TiO), with non-solvent induced phase separation. The resulting films exhibit structural asymmetry. For example, the films have a thin nanoporous surface layer on top of a macroporous finger-like support layer. Parameters that may dictate membrane morphology include the fraction of inorganic nanoparticles used and the length of time allowed for surface layer development. In filtration tests, the resulting membranes show both desirable selectivity and permeability. The synthesis methods for hybrid membranes provide a new self-assembly platform upon which multi-functional and high-performance organic-inorganic membranes can be formed. 1) An asymmetric organic-inorganic film comprising:a multiblock copolymer having at least two blocks that microphase separate; anda plurality of inorganic nanoparticles disposed within at least a portion of the film and on at least a portion of the film surface,wherein the film has a surface layer having a thickness of 20 nm to 500 nm and a plurality of pores having a diameter or equivalent circular diameter of 5 nm to 100 nm in size, andthe film has a support layer having a thickness of 5 microns to 500 microns and pores having a diameter or equivalent circular diameter of 1 micron to 50 microns.2) The asymmetric organic-inorganic film of claim 1 , wherein a dimension of the pores increases in size moving away from the surface of the surface layer in contact with the support layer towards the surface of the support layer in contact with the substrate.3) The asymmetric organic-inorganic film of claim 1 , wherein a plurality of the pores in the support layer lying on a plane 20 microns from the surface layer and parallel to interface between the ...
